Identify Solutions – Solutions that address and correct the root cause.
Solutions determined
to be the best of all the alternatives. Document and verify the Permanent Corrective Action (PCA) in the
Action Item Table.
Validation - Implement and validate to ensure that corrective action does “what it is supposed to
do.” Detect any undesirable side effects. Document this on the Action Item Table. Return to root cause
analysis, if necessary.
Prevention (Design / Information Systems Review) - Determine what improvements in
systems and processes would prevent problem from recurring. Ensure that corrective action remains in
place and successful.
Address Similar Systems - List similar systems.
Assign Action Item and Individual to
Follow Up to correct products/ machine with the potential for the same defect.
